Why do cars need to be soundproofed? Is it necessary for the car to be soundproofed

What are the benefits of doing sound insulation.

1. Sound insulation: The automobile sound insulation project can effectively eliminate and block the engine noise, vibration, resonance of the body door, friction sound generated by the road surface and air resistance when driving, etc., giving you a quiet driving space and greatly improving the comfort of driving. 2. Heat insulation:

The sound insulation project not only insulates the sound, but also effectively blocks the high temperature generated by the engine work, improves the air conditioning effect, and makes you feel cooler.

3. Strengthen the body: the body cover, door, trunk compartment, roof, and key parts of China and Africa are relatively weak, and after the installation of sound insulation materials, the body is stronger, and the passive safety factor is improved in the event of a collision.

4. Optimize the sound effect: The audio, especially the subwoofer installed in the rear, will cause the trunk to vibrate and reduce the sound effect, because the structure of the car cannot withstand the impact of the super bass and make a "squeak" sound. After the sound insulation construction, the resonance of the body metal is eliminated, and at the same time, it has a good sound absorption effect, and the sound can be felt more clear, rich and surging.

5. Reduce the noise in the car: sound insulation can reduce the noise in the car and improve the comfort of driving, after the whole car is soundproofed, when the speed is 100 kilometers, it can be reduced by 3-8 decibels, and the noise level at this time is equivalent to the sound of 60 kilometers without sound insulation.

Which parts need to be soundproofed.

1. Hood: It is an auxiliary part to isolate the sound of the engine, and at the same time can insulate heat and protect the paint surface of the hood.

2. Front fender: suppresses its own resonance, and is also an auxiliary part of tire noise.

3. Fire retaining wall U groove: the main part of the engine is soundproofed together with the sole plate of the main and co-pilot's feet, which can form a more complete sound insulation barrier.

4. Cockpit floor: suppress the resonance of the bottom of the car and block road noise.

5. Four doors: suppress door resonance, block external environmental noise, and improve the sound effect.

6. In the trunk (including rear fenders and rear tailgate): reduce trunk resonance, block rear wheel noise and road noise, and absorb cavity resonance.

7. Four-wheel support outside the car: it is a strengthened part of the tire noise.

Why do you need sound insulation for your car? Today, regardless of home audio or car audio, as long as it is the pursuit of high-quality sound experience, then.

Reducing environmental noise is a must.

Have you ever had this kind of experience, when other riders ask you why you don't install a better set of audio equipment, you can only be:

The car is so noisy to drive, and it is a waste to install such good equipment! Three years ago, we were ashamed to encounter a lot of such questions.

I actively started to study car sound insulation, and the result was echoed by the majority of car friends, only to know that there are so many people who are eager to do so.

Tranquility and comfort in the carriage.

I believe that car owners who have changed cars have an experience that when a new car is bought, it feels the best to drive, quiet, solid and stable.

Shu again. Suitable, yet open.

After three or four years or even one or two years, I feel that some parts of the car, such as the chassis and doors, are loose, or.

There are a lot of abnormal sounds, which are mainly due to the poor assembly quality of the car factory, and the humid climate or some accessories or disassembly and assembly of some parts.

Some of them are not strictly reloaded. Let's ask which car owner doesn't want his car to be driven for a few more years, don't two

After three years, the car drove like it was going to fall apart, and I wanted to change to a new one.

We've also seen a lot of friends install subwoofers, and as a result, the door trim panels vibrate, making it a lot of money.

The sound is not at its best. Car soundproofing can make up for these problems that a new or old car will encounter, it can.

In order to strengthen the structure, it can also strengthen the steel plate of the chassis to avoid premature metal fatigue and fill the gap caused by long-term vibration or.

The abnormal sound caused by poor disassembly and assembly has the function of anti-rust, which improves the bass quality of the audio, so that the car can drive for a few more years.

Feel stress-free, more comfortable, and smoother, the same.

It can also save some vehicle replacement costs. If you want the sound.

If it's better, you shouldn't hesitate. Imagine.

A Xiali flower has the feeling of a high-end car for a few hundred yuan, so that.

The investment value is too high!

What are the benefits of soundproofing my car?

1. For private cars: protect your physical and mental health, care for your family, improve the quality of the car, and enhance the comfort of riding.

2. For business vehicles: speeding on the highway, the quiet environment in the car enables you to get a good negotiation atmosphere.

For audio lovers: Eliminate bass afterglow and improve the overall effect.

There is no need for the car to do sound insulation, reasons: 1. Most of the current car interior parts are snapped, and they are loose after disassembly, which means that there will be a little more or less abnormal noise when driving on bumpy roads, so it can only be counterproductive;

2. If the connection part is not installed to the original standard, it will lead to ash leakage, for example: the plastic paper inside the door trim panel is used to prevent dust from entering, if it is not properly disassembled and assembled, it will cause the glass regulator to lift unsmoothly, the door lock hairpin, etc., replaced with a so-called soundproof paper, the sealing effect is definitely not as good as the original plastic paper;

3. The so-called sound insulation material is just made of asphalt for paving, the temperature in the car is higher in summer, sometimes the vehicle can not avoid parking under the scorching sun, and the vehicle is parked in a small bush under the scorching sun in summer, and the temperature in the car is at least about 60 degrees;

4. It is conceivable that the heat insulation material will release how much poisonous gas will be released by the action of high temperature, and if a pregnant woman sits in such a car for a long time, how much impact will it have on the fetus, and the possibility of causing malformations is also there.

Millions of car purchase subsidies.

I firmly believe that many car lovers have a headache about the noise of their own vehicles, and are ready to make a soundproof modification to the car. Is it reasonable for a car to be soundproofed as a whole car? How much does it cost to complete the soundproofing of the car?

Indeed, the whole car sound insulation is the best effect in the car sound insulation, but it is necessary to do the whole car sound insulation or depending on the situation, otherwise all cars are made full car sound insulation, which is very costly. Because there are some cars, their own sound insulation effect is not low, or only a certain part of the sound insulation is not in place, at this time there is no need to do the whole car sound insulation, only for a certain part of the sound insulation will have a very large effect.

The whole car sound insulation is a systematic modification project, from the first we can see how many processes, which means that the whole car sound insulation is very car dry an internal plastic surgery, if there is a slight impropriety or not very technical professional, it is very easy to cause complications to the car. Therefore, car soundproof modification must find a reliable and professional modification shop to do.

According to the different sound insulation raw materials, the price of the whole car sound insulation will also have a certain difference, expensive to go to 78000, cost-effective 34000 is also available, but we propose to choose reliable raw materials, at this stage the market in the soundproof goods are varied, soundproof raw materials are very important, and sound insulation effect, environmental protection, and even physical and mental health are quite related.

Some consumers will insulate the car after buying it, because it can ensure that the car is quieter, but some people think that it is not necessary. () Bian Xiao will tell you the hazards of sound insulation.

The Dangers of Sound Insulation in Cars: An Introduction.

After sound insulation, there will be a certain effect. The sound insulation depends on the quality of the material and the placement location. Soundproofing throughout the car includes:

hood, fenders, chassis, trunk, tailgate, headline, firewall. Generally speaking, the sound insulation of the whole vehicle in the audio modification shop only includes: hood, fender, chassis, trunk, and tailgate.

Moreover, the ceiling and the firewall are charged separately, and the firewall alone costs 2500-3500. Look at the main models. All dashboards should be taken apart and glued inside.

However, just the hood, fenders, chassis, trunk, tailgate are about the same. All came down. General materials range from 2000 to 3600.

The charge mainly depends on the vehicle type. The big car is a little more expensive, and the small car is a little cheaper at the low end.

The Hazards of Sound Insulation in Cars: Functional.

Reduce the noise in the car: The automobile sound insulation project can effectively eliminate and block the roar of the engine, the vibration of the body, the friction of the wheels and other noises. This creates a quiet interior and improves passenger comfort. After construction, the noise can be reduced by 7 8db.

Improve the sound effect: After the implementation of the car sound insulation project, the resonance of the body metal is eliminated, and at the same time, it has a good sound absorption effect, making the sound clearer, richer and stronger.

Reduce the temperature in the car: The sound insulation project can not only insulate the sound, but also insulate the heat, which can keep the high temperature of the engine out of the car, thereby reducing the temperature in the car.

Delay the aging of the paint film: The high temperature of the engine is easy to make the paint film aging and discoloration, and the implementation of the sound insulation project can effectively isolate the sound, which has an excellent protective effect on the automotive paint film.

That is where car sound insulation is done and the hazards of car sound insulation introduced above. In general, soundproofing of the car is necessary. If you want to be quiet in the car, you can make a soundproof for the car.
